Title: Semi-automatic firearm
IPC: F41A3/00
Filed: 1974-08-28
Abstract: 1439309 Firearm F S THOMAS 28 Aug 1974 [4 Sept 1973] 37561/74 Heading F3C A firearm comprises a frame 17, Figs. 2, 3 and 4, having a hand grip 67, a barrel 15 which is supported by the frame 17 and has a firing- chamber 31, a slide-member 21 which surrounds the barrel 15, a spring 25 which is located between the slide-member 21 and the barrel 15 and urges the slide-member 21 towards the muzzle of the barrel 15, a firing-pin 41 axially movable within the slide-member 21, a spring 49 which is positioned between the firing-pin 41 and the slide-member 21 and urges the firing-pin towards the muzzle, the spring 49 being stronger than the spring 25, a trigger 57 pivotally mounted on the frame 17, a triggerbar 73 which is movable by the trigger 57 to engage the firing-pin 41 and move it in the direction away from the muzzle and then release it, and a lever 95, Figs. 5 and 6, which is pivotally mounted on the frame 17 and can restrain the slide-member 21 against movement relative to the frame when the hand grip 67 is grasped by a shooter. In use the pulling of the trigger 57 urges the shooter's hand against the lever 95 and forces legs 103 thereof into recesses 113 and prevents the slide-member 21 from moving rearwardly. A sear 83, Figs. 3 and 4, on leg 79 of the triggerbar 73 engages a sear 51 on the firing-pin 41 causing the rearward motion of a trigger-bar 73 to move the firing-pin 41 rearwardly, and the spring 49 is compressed. At a predetermined position of the trigger 57, the leg 79 of the trigger-bar 73 disengages the sear 83 from the sear 51, the spring 49 overcomes the force of a firing-pin return-spring 45 so as to thrust the firing-pin 41 forwardly, and a cartridge 33 is fired. Gas pressure generated urges a leg 101, Figs. 5 and 6, of the lever 95, to cause the legs 103 to abut the recesses 113 and retain the slide-member 21. The recoil force exerted rearwardly against the slide 21 is greater than the force exerted by the lever 95, thus the legs 103 leave the recesses 13 and the slide 21 is released to move rearwardly. The latter is retarded by lips 111 thereof being in frictional contact with the legs 103 of the lever 95. A magazine safety bar 125, Fig. 2, is attached by a pin 127 to the hand grip 67 and extends into a magazine receiver 69. An end 129 of the bar 125 is alignable with leg 81 of the trigger-bar 73 and, when aligned, prevents the bar moving rearwardly and the weapon from being fired. A portion 131 of the bar 125 is engaged by a magazine 71 which is in the receiver 69. The bar 125 is moved sideways so that its end 129 is out of alignment with the leg 81. The triggerbar 73 is then free to move rearwardly when the trigger 57 is actuated. A slide lock is provided to secure the slide 21 in its fully open position after the last round in the magazine 71 is inserted in the chamber 31. An extractor 157, Fig. 3, having a claw 155, removes the spent cartridges from the firing- chamber 31.

Title: Fluid operated valves
IPC: F16K31/363
Filed: 1962-10-05
Abstract: 948,425. Valves. ROSS OPERATING VALVE CO. Oct. 5, 1962 [Nov. 27, 1961], No. 37841/62. Heading F2V. A valve 37 comprises a spool slidably mounted in a body 35, an inlet chamber 41 connectible to a source of constant pressure, such as the inlet 15 of a main valve 22, a signal chamber 54 alternately connectible by a valve 32 to pressure and exhaust, axially spaced inlet and exhaust valves 46, 48 carried by the spool, a working port 59 between the inlet and exhaust valves, an exhaust port 55 between the exhaust valve 48 and the signal chamber, and a seal 44 separating the exhaust port and the signal chamber, the relative areas of the valves and seal being such that part opening of the inlet valve 46 causes the spool to shift rapidly fully to open the inlet valve 46 and part opening of the exhaust valve causes the spool to shift rapidly fully to open the exhaust valve 48. When the valve 32 is connected to pressure a restriction 29 permits a gradual pressure increase in the chamber 54 moving the spool to the right against the resistance of inlet pressure in the chamber 41 until the exhaust valve 48 closes by entering a bore 43, and subsequently, the inlet valve 46 opens by leaving a bore 42. Inlet pressure is now able to act on both sides of the seal 46 and the spool is moved rapidly to the right to open the port 59 fully and allow the main valve 22 to connect a working port 17 to exhaust 16 instead of the inlet 15. Connection of the chamber 54 by the valve 32 to exhaust permits a rapid fall of pressure through a check valve 28 so that the spool is returned to its original position by the inlet pressure in chamber 41. The check valve may be reversed. In a modified arrangement, both supply and exhaust flows to the chamber 54 are restricted and an additional fluid-actuated valve is provided between the chamber 54 and the bore 42 so that the chamber 54 is connected with the inlet chamber 41 and with the exhaust port 55 as soon as the inlet and exhaust valves 46, 48 are opened.

Title: Improvements in or relating to the manufacture of synthetic resins
IPC: C08G8/06
Filed: 1928-12-24
Abstract: 326,884. Wade, H., (Bakelite Corporation). Dec. 24, 1928. Cresol-furfural condensation products. - An intermediate resinous condensation product is first formed by reacting upon cresol with furfural in the presence of a limited amount of a basic condensing agent, the reaction being carried out under a reflux condenser, and so controlled as to yield a highly fusible product which does not, on cooling, harden to a brittle mass. 'Thereafter, the resin is transferred to an open mixing machine, a further amount of the basic condensing agent added and the reaction carried to completion. It is important to avoid the presence of material quantities of phenol during the first reaction stage. During the second reaction stage a fusible natural or synthetic resin, or a plasticizing agent may be added. The resulting product is rendered infusible and substantially insoluble in ordinary solvents by sufficient application of heat. If it is mixed with a non-reactive phenolic resin an amount of hexamethylenetetramine or equivalent hardening agent is preferably added. An example is given in which furfural is condensed with cresol in the presence of calcium hydroxide, the latter being added in two stages. Other suitable condensing agents are the oxides of calcium or magnesium and the carbonates or hydroxides of sodium and potassium, and the like. Specification 138,061 is referred to.

Title: Charge-coupled circuits
IPC: G11C19/28
Filed: 1972-08-16
Abstract: 1395558 Charge-coupled devices RCA CORPORATION 16 Aug 1972 [19 Aug 1971] 38171/72 Heading H1K A 2-phase operated CCD has alternate adjacent pairs of capacitative electrodes 10-1, 12-1; 10-2, 12-2 &c., connected to the # 1  and # 2  lines respectively, and each pair of electrodes has asymmetric provision for the storage of fixed charge in the dielectric. This ensures that charge transfer proceeds in one direction only. The fixed charge under one electrode may be zero and under the other either positive or negative; or the fixed charges under both electrodes may be of the same sign but of different magnitude; or the fixed charges under the two electrodes may be opposite in polarity. As described, devices use P-type or N-type silicon substrates and an electrode sequence using both aluminium and polycrystalline silicon electrodes. Preferred devices use fixed charge storage only under one electrode of each pair, and this may be a negative charge stored in alumina or a positive charge stored at the interface between superposed layers of silicon nitride and oxide (as shown). In both cases the fixed charge may be inserted by the application for a short period of a voltage 3 or 4 times greater than those applied to the electrodes in normal operation. With alumina insulation the fixed charge may result from its method of deposition. The device input may use illumination or a source electrode and the device may be operated with a substrate bias. By suitably arranging fixed storage polarity and substrate conductivity type, prominence in operation may be given to the use either of potential wells or of potential barriers. In the latter case all or only part of the movable charge under an electrode pair may be transferred to the adjacent pair.

Abstract: 1,045,279. Seaming. TANNOID Ltd. Oct. 9, 1963 [Oct. 10, 1962], No. 38420/62. Heading B5K. A method of joining heat-weldable strip material comprises laying the parts to be joined one over the other, placing a band of heat-weldable woven material around the strips so as to enclose the area of the join and applying heat and pressure to the area. The pressure is preferably maintained while the parts cool. The strips and the band may be of cotton, linen, nylon, rayon or glass and coated with polyvinyl chloride or other thermoplastics material or with unvulcanized rubber. Strips 14, 15 are placed in overlapping relation in a die cavity provided between plates 1, 2 which areheated by electrically-heated platens (not shown). The die cavity may be tapered (Fig. 4, not shown), or may be provided with a central depression to accommodate more than two overlapping layers of straps (Fig. 5, not shown). Joins may be made at several, say five, positions along plates 1, 2 by constructing the plates of appropriate configuration (Fig. 1, not shown). Preferably the upper heating platen is mounted on a horizontal axis for movement in relation to the lower, fixed platen. The platens may be maintained at about 200‹ C., but the time of pressing may be reduced by employing higher temperatures. If required, weights may be hung on the upper platen. Stainless steel strips are placed above and below the strip material to avoid uneven edges to joins.
